Data Aggregator Validation Early Adopter Phase Launched

The pilot has been completed and NCQA has launched the Early Adopter phase of the Data Aggregator Validation program.

The DAV program validates organizations (e.g., health information exchanges) that collect, aggregate and transform data from original data sources on behalf of vendors and health care organizations.


Rules for HEDIS reporting require Licensed Organizations to go back to the original data sources to check validity during a HEDIS audit®.

The time and expense to verify original source data discourages plans from working with data from aggregators. The DAV program alleviates this issue:

  • The DAV program checks data coming into and going out of aggregators so health plans and auditors don’t have to do it during a HEDIS Audit.
  • “Validating the aggregator” improves the ease and accuracy of HEDIS data collection and reporting.


  • Validation of Input: NCQA checks completeness, accuracy and reliability of data that aggregators ingest from EHRs, labs, pharmacies and other sources.
  • Validation of Output: NCQA checks that aggregators can produce a Continuity of Care Document (CCD)—data in a standardized format that the aggregator can pass to health plans for HEDIS reporting.
  • An Opportunity to Grow: Data hubs that earn NCQA Validation become “standard supplemental data” sources for health plans, making data aggregators attractive partners for health plans and enhance their role in quality reporting.

Eligibility would be broad. Almost any hub that aggregates data would potentially qualify to earn the NCQA seal if it meets program standards:

  • Commit staff as necessary to complete validation during the 12–15 week program.
  • Use technology to conduct internal data quality reviews of all ingested clinical data sources and produce standard reports.
  • Produce and transmit an aggregated CCD that conforms with NCQA’s CCD Implementation Guide.
  • Exchange aggregated data (CCDs) with health plans to support quality reporting programs.
  • Meet the requirements of primary source verification, including getting records from ingestion sites.
  • Have data rights agreements in place, including the ability to resend clinical data to validators and NCQA on request.

NCQA is developing a program for technology vendors that may not meet all DAV program criteria but are interested in having their solution “prevalidated” for the program.

Annual revalidation is required to maintain the DAV seal.


NCQA completed the DAV program pilot project in October 2020 and announced the results in November. Three HIEs in New York state earned “Validated with Exception” status and each has the ability to share validated clinical data sources as standard supplemental data for use in HEDIS MY 2020 reporting.

The Early Adopter phase of the DAV program began in November and ends in February 2021. Its purpose is to work with various types of organizations and identify additional operational and customer support needs.

NCQA plans a full program launch in summer 2021 and will communicate related information as it becomes available.
